A custody hearing for temporary guardianship of Michael Jackson's children scheduled for Monday has been rescheduled for July 20 at the request of Katherine Jackson and Debbie Rowe, according to court officials.

"All prior orders remain in full force and effect, with Katherine Jackson as temporary guardian of the children," according to a Los Angeles Superior Court statement released Friday afternoon.

Michael Jackson's kids – Prince Michael I, 12, Paris, 11, and Prince Michael II (Blanket), 7 – have been living with their grandmother, Katherine, and staying at her Encino, Calif., home since the death of the pop icon on June 25.

Rowe, who is the biological mother of Prince and Paris, has not filed a petition for temporary guardianship, says a courthouse spokesperson. Blanket's mother has never been identified.

Last week, Rowe's attorney Eric George, said, "The truth is that Debbie has not reached a final decision concerning the pending custody proceedings."

This came on the heels of Rowe telling her former attorney and close friend Iris Finsilver that she intended to pursue custody. "Frankly, she won't have to fight for them, " Finsilver told PEOPLE. "She is the children's biological mother. She loves her children."

But Jackson's mother, Katherine, was named the guardian of his three children in his will, which was revealed last week. A source close to the family says of the Jacksons: "They will fight."
